Abstract L’hormonorésistance acquise constitue l’un des défis majeurs dans le traitement du cancer du sein avancé exprimant le récepteur aux estrogènes (RE) et sans surexpression de HER2. Les mutations activatrices du gène ESR1 affectant le domaine de liaison du ligand ont récemment été identifiées comme l’un des principaux mécanismes de résistance aux inhibiteurs de l’aromatase (IA). Ces mutations peuvent être recherchées sur des prélèvements histologiques ou sur ADN tumoral circulant, par PCR ou séquen- çage de nouvelle génération (NGS). Elles induisent une activation constitutionnelle du RE conduisant à une résistance acquise aux IA ; le tamoxifène, le More >

Abstract The hemodynamic effects of a patent ductus arteriosus (PDA) are well known including systemic hypoperfusion and volume overload on the left ventricle. This article aims to provide a review of the long-standing effect of a hemodynamically significant PDA on the pulmonary vasculature and the role of cardiac catheterization in preterm infants with a PDA and pulmonary hypertension.

Abstract The aim of this study was to determine the relationship between phenotypic antimicrobial susceptibility patterns and extended-spectrum, carbapenem-resistance genes. A total of 109 clinical Staphilococcus aureus strains were subjected to 19 antimicrobial susceptibility tests. Resistance to methicillin (mecA), penicillin (blaTEM), and tetracycline (tetM) was detected. We compared the presence of the blaTEM genes with extended-spectrum, carbapenem-related genes and identified the types of SCCmec genes. Of 109 clinical S. aureus strains, 62 (56.88%) had methicillin resistance and 60 strains carried mecA. The prevalence of blaTEM and tetM genes was 81.65% and 37.61%, respectively. The most predominant SCCmec type More >

Abstract X-ray repair cross-complementing protein 1 (XRCC1) could repair cisplatin-induced DNA damage. XRCC1 Arg399Gln and Arg194Trp variants alter XRCC1 expression and function, leading to changes in cancer sensitivity to cisplatin treatment. This study aimed to investigate the effects of XRCC1 Arg399Gln and Arg194Trp polymorphisms on cell viability, apoptosis and XRCC1 expression in cisplatin-sensitive A549 and cisplatin-resistant A549/DDP nonsmall cell lung cancer (NSCLC) cells. Plasmids carrying XRCC1 Arg399Gln and Arg194Trp were constructed and transfected into A549 and A549/DDP cells. RT–PCR, Western blot, MTT assay, and flow cytometry analysis were performed to assess cell viability, apoptosis, and More >

Abstract This work aimed at analyzing the petroleum adsorption capacity and the compressive strength of cellulose cryogels produced with the addition of 4 and 8% (w/w) sodium hydroxide (NaOH). Cryogels were produced from a 1.5% (m/m) suspension of cellulose microfibers, which originated from Pinus elliotti, in distilled water. The addition of NaOH increased the compression strength of cryogel by 30% when compared to cryogel without the reagent. Due to the 50% decrease in volume, the cryogel FLNB-8h (8% NaOH) has its petroleum adsorption capacity decreased in average by 58%, whereas the FLNB-4 (4% NaOH) cryogel had More >

Abstract This study was to provide a new aspect of application of shape memory alloys (SMAs) in civil engineering. The high-density polyethylene (HDPE) have been used for construction of pipelines for several years. The main problem of using HDPE for pipes is the joint of two adjacent pipes. In case of having a perfect joint, the HDPE pipeline can bare the internal pressure up to 90 MPa. However, in practice, it can rarely achieve to a perfect pipe joint due to the complicated process, so, it prone to fracture in low internal pressure. To overcome this,… More >

Abstract This paper studies the effect of ice resistance on the icebreaking capacity and speed of an icebreaking vessel. We combine an improved Correct Smoothed Particle Method (CSPM) with a material low-speed collision fracture model to numerically simulate the continuous icebreaking and rolling process of crushed. Using this model, we investigate the icebreaking resistance and immersion resistance during the icebreaking process, taking into account the fluid (water) as the elastic boundary support and the fluid-solid coupling interaction. We compare the icebreaking resistance and broken ice fracture shapes obtained by the numerical calculation with the theoretical analytical More >

Abstract The use of magnesium alloys has been rapidly increased due to their ability to maintain high strengths at light weights. However weldability of steels and aluminum alloys by using resistance spot weld (RSW) process is a major issue, because it cannot be directly utilized for magnesium alloys. In this study, a structural-thermal-electrical finite element (FE) model has been developed to predict the distribution of residual stresses in RSW AZ61 magnesium alloy. Thermophysical and thermomechanical properties of AZ61 magnesium alloy have been experimentally determined, and have been used in FE model to increase the accuracy of… More >
